The most yummy thing that we've made in Food & Fitness class to date has been these granola bars. I made them at home with the recipe modified to my liking.
First, the wet mixture: 1/2 cup butter, 1/4 cup sugar, 1/3 cup honey, 1/4 cup flour, 1/2 teaspoon vanilla extract, 1/2 teaspoon cinnamon.
Then the dry mixture: 2 cups puffed wheat cereal, 2 cups rolled oats, 1 cup dried apricot (chopped), 1/2 cup salted almonds, 1/4 cup dark chocolate chips.
Combine the two mixtures and drop into a greased 9 x 13 pan. To press the mixture down without getting your hands all sticky, use a greased piece of parchment paper.
Bake in a 350F oven for 20 minutes or until golden. Then let cool for at least an hour before attempting to cut it. Mine didn't cut very well but you might be able to avoid that problem with either a little more honey, or a little more hardcore cooling (in the fridge or freezer).
Feel free to substitute with your own favorite puffed cereal, dried fruits, nuts/seeds, etc!
